*Decide after the privacy amplification process, the key reduction amount is calculated by the system or decided by the user.
:Note:If calculated by the system, the formula is:
:paKeyLength_tmp = [[@ECKEY LEN BLOCK]] - eve_info_estimate - safe_factor
:[I(Eve_shannon_info) <= 2^(-s)ln(2) ; s = safe_factor]
:[eve_info_estimate = [[@ECKEY LEN BLOCK]]*binary_entropy_function(QBER)]
:[binary_entropy_function(x):y=-x*log2(x)-(1-x)*log2(1-x)]
*Is store as '''autoPaLength''' in the fortran code.

example
 @AUTO_PALENGTH
 .TRUE.

Which mean the key reduction amount will calculated by the system like the formula above.
